Description

BACKGROUND OF THE INVENTION

Cargo straps are commonly used on trucks, especially flat bed trucks, to secure loads. Various winch devices are used, with some more prevalent than others. Many such winches include a projecting portion with one or more radial holes for using a lever or lever bar of a chosen type to wind the winch, thereby tightening straps. One problem with strap winches is that operators often use any available bar or the like to tighten the winches. Often, any available bar or the like is used to tighten the winches, with the winches and the bars suffering the expected damage therewith associated. A number of devices have been provided to assist in winding such winches. Many of these devices do not offer proper winch driver engagement, nor sufficient leverage for tightening the winch straps. The devices known do not incorporate the advantages of the present ratcheting apparatus used in winding the winches of cargo straps.

FIELD OF THE INVENTION

The ratcheting apparatus for cargo strap winches relates to devices used in winding winches for securing trailer straps and therefore trailer cargo, and more especially to a ratcheting apparatus for cargo strap winches which offers secure, quick engagement and disengagement from a winch, and proper leverage for tightening winch straps.

DESCRIPTION OF THE PRIOR ART

Prior related art U.S. Pat. No. 6,467,755 issued to Reilly et al. on Oct. 22, 2002 teaches a power driven winch winding tool. The tool being power driven differs from the present leverage bar apparatus. U.S. Pat. No. 5,775,175 issued to Salemno et al. on Jul. 7, 1998 teaches a device for winding a crank and associated method. The device is geared and does not provide the same engagement or drive method of the present apparatus. U.S. Pat. No. 6,102,637 issued to Mocci on Aug. 15, 2000 teaches a flatbed wind winding bar that engages a winch. The bar does not provide the leverage nor the ratcheting action of the present apparatus.

DETAILED DESCRIPTION OF THE DRAWINGS

With reference now to the drawings, and in particular FIGS. 1 through 4 thereof, the principles and concepts of the ratcheting apparatus for cargo strap winches generally designated by the reference number 10 will be described.

Referring to FIGS. 1 and 2, the ratcheting apparatus 10 for engaging a driver 102 of a cargo strap 110 winch 100 comprises a cylindrical engagement sleeve 12. The engagement sleeve is for fitting over the driver 102 of the winch 100. The engagement sleeve 12 has a diameter, a first end and a second end. An orifice 16 is disposed in an each side of the engagement sleeve 12. The orifices 16 are proximal to the first end of the engagement sleeve 12. The cross bar 20 is for removable fit through the orifices 16 and thence through any of a plurality of drive holes 104 in the winch driver 102. Each orifice 16 is preferably comprised of one orifice flat side 18. The cross bar 20 is preferably comprised of one matching cross bar flat side 22, providing a secure, removable cross bar 20 fit within the orifice 16. A series of teeth 24 is disposed on the second end of the engagement sleeve 12. A plate 26 is disposed within the engagement sleeve 12. The plate 26 substantially fills the inner diameter of the engagement sleeve 12. The ratcheting sleeve 14 is of an equal diameter to the engagement sleeve 12. The ratcheting sleeve 14 has a first end and a second end. A series of teeth 24 is disposed on the first end of the ratcheting sleeve 14. The ratcheting sleeve 14 teeth 24 are for engaging the teeth 24 of the engagement sleeve 12. The engagement sleeve 12 teeth 24 and the ratcheting sleeve 14 teeth 24 cumulatively ratchet freely in a one direction and engage in an opposite direction. The teeth 24 engage in a tightening movement for the winch 100. A pair ratcheting sleeve 14 openings 15 is disposed in the ratcheting sleeve 14. The openings 15 are proximal to the second end of the ratcheting sleeve 14.

The apparatus 10 is further comprised of a rod 30. The rod 30 has a first end, a second end, and a length therebetween. The rod 30 is for removable insertion through the plate foramen 28 of FIG. 3 of the engagement sleeve 14 and the ratcheting sleeve 12 plate 26 foramen 28 of FIG. 4. The handle 34 is disposed on the second end of the rod 30. The spring 36 freely encircles a substantial area of the length of the rod 30. A release pin 44 of FIGS. 3 and 4 is disposed within the length of the rod 30. The release button 42 is disposed on the handle 34. The leverage bar 46 fits within the ratcheting sleeve 14 openings 15. The leverage bar 46 is of a metal of sufficient strength to resist bending in use. The leverage bar 46 metal is preferably hardened.

Referring to FIG. 3, the plate 26 is disposed within the ratcheting sleeve 14. The plate 26 substantially fills the inner diameter of the second end of the ratcheting sleeve 14. The foramen 28 is disposed in a center of the plate 26. The foramen 28 provides for removable insertion of the rod 30. The detent balls (not shown) of the rod 30 prevent removal of the rod 30 through the plate 26 until the release pin 44 of the rod 30 is depressed. The detent ball and functions of same are well known in the mechanical arts. More than one detent ball is disposed on the first end of the rod 30. Depression of the release button 42 moves the release pin 44 to release the detent balls.

Referring to FIG. 4, the engagement sleeve 12 comprises a plate 26. The plate 26 substantially fills the inner diameter of the engagement sleeve 12. A foramen 28 is disposed in the center of the plate 26. The foramen 28 slideably and removably receives the rod 30. The detent balls (not shown) of the rod 30 prevent removal of the rod 30 through the plate 26 until the release pin 44 of the rod 30 is depressed.

In use, the apparatus 10 is acquired and the engagement sleeve 12 removably fitted around the driver 102 of a winch 100. The cross bar 20 is fitted through one engagement sleeve orifice 16, thence through the drive holes 104 of a winch 100 driver 102, thence through the opposite engagement sleeve orifice 16. Although the engagement sleeve 12 and ratcheting sleeve 14 are separable, it is customary to leave the two engaged together by the detent balls of the rod 30. The ratcheting sleeve 14 is thereby engaged with the engagement sleeve 12 via the teeth 24 of each. The spring 36 of the rod 30 provides correct engagement tension. The spring base 38 provides a spring contact surface against the handle 34. The apparatus 10 is removably fitted to the winch 100 driver 102. The cross bar passage 23 allows leverage bar 46 fit. The leverage bar 46 is then used to tighten the strap 110 on a winch 100. Once straps 110 are tightened, the cross bar 20 is removed to allow removal of the apparatus 10 from the winch 100. The apparatus 10 can be hung on a tool rack or the like by the handle ring 40 for convenience.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the ratcheting apparatus for cargo strap winches, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the ratcheting apparatus for cargo strap winches.

Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the ratcheting apparatus for cargo strap winches may be used.

Therefore, the foregoing is considered as illustrative only of the principles of the ratcheting apparatus for cargo strap winches. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the ratcheting apparatus for cargo strap winches to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the ratcheting apparatus for cargo strap winches.
